Researchers have presented several approaches to select the best task flow in a shop floor context using case-based reasoning and heuristic search techniques Aytug et al. 2005 . This model uses a rule-based reasoning approach with learning abilities. Two kinds of deliberative behaviors have been identified Anticipation and Negotiation behaviors. Anticipation behaviors consist in using partners models in addition to the agent s own local model. Basically it concerns integrating information about partners into its planning behavior. Collaboration between planning partners through anticipation has been studied in hierarchical relation types to improve decision making Schneeweiss Zimmer 2004 . Anticipation in supply chain planning can be interesting in situations where communication is limited or time is constrained. For example a drying agent can use an internal model of its partner the finishing agent to supply it with alternative products if the required ones are not available in time. Negotiation behaviors involve some forms of exchange with partners during planning. This may take the form of proposal and counter proposal . Contract Net alternative demand and supply plans . For instance when the agent is not able to respond to its partner s needs it can offer changes in delivery dates or alternative products. Following this an iterative exchange of proposals is started where both agents try to find a compromise. These proposals can take the shape of new constraints which can be used by partners to re-plan production and send a new demand plan. When the agent planning phase is ended the next phase is the execution of the task flow which is mainly the allocation of resources machine labor etc. to specific production tasks. Using a pre-determined algorithm a production plan is built creating demand plans for suppliers and supply .
